Launching

The launch form takes name, symbol, a logo (cropped and pinned to IPFS; the chain stores ipfs://CID), description, and the books you want. You may paste an ipfs://, ipns://, or https:// URI instead. Quote preview is in USD because every book quotes a dollar stable. The 1% take split is not a choice: 90% creator, 10% platform. You may add 0–3% extra creator tax — a live take, not a stored term. Payout defaults to the deployer and can be redirected later.

Salt

The app (or a miner) finds a userSalt so the CREATE2 address ends in aaaa. Recompute the same salt from on-chain data when you extend.

Launch fee

Print costs $1 in that book’s quote: USDG on Robinhood, USDT on BSC, USDC on Arc. Same dollar, local stable. Paid to the protocol recipient on that chain. Not ETH, not BNB, not native Arc USDC. Owner can change the amount or switch it off. Each book you print is a separate launch, so three books are three print fees. A LayerZero extend pulls the fee from the deployer on the destination book — approve the factory there first.

Official $SMCA

$SMCA is the pad token of Sameca launchpad. It prints on Pons (Robinhood Chain, USDG) and Argus (Arc, USDC) together. Two venues, two inventories. Sameca Launch must not offer a checkbox for SMCA. Do not mint it through SamecaFactory.
